Moffat function
WebThe basis function methods use smooth functions which have explicit formulas and easily to be created. As our test results have shown, Moffatlets performed better in image reconstructions than Gaussianlets. This is mainly because the Moffat function is a better PSF model than the Gaussian function.

WebThe Point Spread Function (PSF) of the astronomical imaging system is usually approximated by a Gaussian or Moffat function. For simplification, the astronomical imaging system is considered to be time and space invariant. This means that invariable PSF within an exposed image is assumed. If real wide-field imaging systems are … Web26 nov. 2024 · The fraction of events in the Moffat function describing the tail was fixed by matching the components at x b = sqrt(20) * σ.

The Moffat distribution, named after the physicist Anthony Moffat, is a continuous probability distribution based upon the Lorentzian distribution. Its particular importance in astrophysics is due to its ability to accurately reconstruct point spread functions, whose wings cannot be accurately portrayed by … Meer weergeven Probability density function The Moffat distribution can be described in two ways. Firstly as the distribution of a bivariate random variable (X,Y) centred at zero, and secondly as the distribution of the … Meer weergeven • Pearson distribution • Student's t-distribution for $${\displaystyle \beta ={\frac {\alpha ^{2}+1}{2}}}$$ • Normal distribution for $${\displaystyle \beta ={\frac {\alpha ^{2}}{2}}\rightarrow \infty }$$, since for the exponential function Meer weergeven Web13 mrt. 2024 · Our methods decompose the star images into smooth principal components by using the Expectation-Maximization-PCA (EMPCA) method, and the smooth principal components are composed by Moffatlets basis functions, which are derived from the Moffat function.
